UNHTEE STATES PATENT QFFHCEO GREASE CUP.

Application filed September 17, 1921.

To all whom it may concern:

Be it known that I, JOHN OWnNs, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Grease Cups of which the following is a specification.

This invention relates to grease cups and more particularly to those grease cups that are to be attached to the bearing parts of automobiles or other vehicles using grease in a semi-fluid condition.

One of the objects of the present invention being to provide a grease cup, the top of which may be readily removed for the attachment of a nozzle.

Another object of my invention is to so connect the parts of the cover of the cup that they will not become readily detached and the parts lost.

With the foregoing objects outlined and other objects in view which will appear as the description proceeds, the invention consists in the novel features. hereinafter described in detail, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

Referring to the drawings Figure 1 is a vertical section of a grease cup attached to the casingof the part to be lubricated;

Fig. 2 is a section of the modification of the cup shown in Fig. 1.

In the drawings 1 designates a cup at tached to the casing 2 of the part to be lubricated. The cup proper has pins 3 which fit in bayonet slots in a surrounding casing 4 snugly fitting the exterior of the cup.

In the form shown in Fig. 1, the part 4 has a shoulder and there is a cover 6 fitting over the part 4, this cover 6 having a ledge 7 and between this ledge and the shoulder 5 there is provided a spring 8 normally separating the ledge 7 and the shoulder 5.

It is apparent from the description of this modification of my invention that when the cylindrical part 4 is forced down over the cup 1 and the pin and slot connect the same to the cup that the spring will force the cover 6 tightly down against the top of the cup 1. At the same time the cup cover may be easily removed for the attachment of a nozzle constructed to co -act with the cup having the pin and slot. connection.

Serial No. 501,238.

Such a nozzle is shown in my copending application above referred to.

In the modification shown in Fig. Qthe spring 8 is placed on the exterior of the part 4 surrounding the cup, the ledge 5 of this part being at the bottom while the shoulder 7' against which the upper end of the spring rests is at the top of the outside cylindrical part 6.

While the top of the cup is shown conical in form it may of course be cylindrical or of any other convenient shape.

From the foregoing I believe that the construction, operation and advantages of my improved cup and connections will be readily understood. by those skilled in the art and I am aware that various changes may be made in the construction illustrated without departing from the spirit of the invention as expressed in the following claims.

I claim as my invention 1. A grease cup comprising a body portion, a cover therefor comprising an inner part fitting around the exterior of the cup and an outer part around the inner part with a coiled spring between the ends of the inner and outer part of the cover for holding the cover top against the top of the cup.

2. A grease cup having a two part cover each part having a shoulder, one extending inwardly and the other outwardly to pres vent separation of the parts, a spring between the shoulders and a detachable connection between'the cup and cover.

3. A grease cup having projections on its exterior, a two-part cover around the cup, each part having a shoulder. one shoulder extending inwardly and the other outwardly to prevent separation of the parts. a spring between the shoulders. and slots in one of the parts to co-act with the projections on the cup to detachably hold it to the cup.

4. A grease cup and a cover therefor. said cover being entirely on the exterior of the cup proper and comprising an inner and outer part with a spring between the parts to hold one part to the cup when the cover is on the cup, and means on the exterior of the cup proper and on one part of the cover which co-act to detachably hold said last mentioned part to the cup.

In testimony whereof I hereunto aflix my signature.

JOHN OWENS.
